Forum: GratefulDead Subject: Re: the wall and how was it wired

if they were in parallel w/ one giant splice per bank to amps how many speakers I'm not so .sure Series on the other hand would more than likely take the load off but if a speaker goes out then I think that whole bamk goes w/ it.
I was an alarm installer for years and the general rule for closed circuit contacts is to be wired in series, again if one door/window opens it sets off the alarm.With fire and panic alarms it's wired in parallel so any device will work and all others would would also Speakers do have resistance 8ohms ect.So how many speakers per bank of amps were wired.I would have loved to see the back of that stage.Not to mention the power needed. As a oft story when I saw Pink Floyd at Yankee Stadium all along Jerome Ave. they had rows of semi trailer generater trucks just puming all the juice that was required. These shows plug strip need not apply.Thanks for the attempt but we need an audio engineer who knows for sure how it was done.
